SANDING DEVICE FOR MOTOIRi-VEHICLES.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, LABS OSCAR LEVIN, a citizen of the United States, and a resident of Vancouver, in the county of Clarke and State of Washington, have invented new and useful Improvements in Sanding Devices for Motor-Vehicles, of which the following is a specification.

My invention is an improvement in sanding devices for motor vehicles, and the invention has for its object to provide means adapted to be arranged in front of the rear wheels of the vehicle for spreading the sand in front of the said wheels, wherein means is provided for permitting the sand to be kept dry by the exhaust from the engine.

In the drawings:

Figure 1 'is a side view of an automobile, provided with the sanding device, and with parts in section;

Fig. 2 isa top plan view of the sanding device detached;

Fig. 3 is a side view of the sanding mechanism, with parts in section;

. Fig. 4 is a bottom plan view of the valve operating mechanism; and

Fig. 5 is a top plan view of the valve aiid its guide.

The present embodiment of the invention is shown in connection with an automobile 1, the sanding devices being secured-to the running-boards 2 directly in front of the 1 rear wheels 3.

Each of the said devices comprises a sub- 'stantially hopper shaped container consisting of aninner wall 4 and an outer wall 5, and these walls are spaced apart and held 6 of corrugated material. Each container is provided with a cover 7 hinged to the container at 8, and having latch mechanism indicated at 10 for holding the cover closed. It will be noted that at their tops the containers in- .cline downwardly'and outwardly, so that the covers are sloping','permittin% access to the containers for permitting t em to be placed near the running-board.

Each container is supported by two pairs of brackets 11 and 12, each bracket being secured *at one end to the container and at the other to the running-board. The exhaust products from the mufiier 13 are ad-' ace between the walls 4 and 5 of the containers'by means of a in e 14 which leads from the muflier to a which is interposed in the length of' the spring 29.

pipe 16 which connects the containers and communicates with the space between the walls 4 and 5 at the tops of the containers. The exhaust products may thus pass freely between the inner and outer walls of the container to dry the sand which is held within the container and to prevent freezing of the sand in cold weather.

The lower end of each container is connected with one of the sections 17 of a valve casing, the said casing consisting of the sections 17 and a lowersection 18. These sections'are secured together, as indicated at 19, and they coiiperate to form a guideway for the slide valve 20 which is arranged he'- tween the casings in the guideway. Each valve is connected by links 21 and 22 with one end of a lever 23, which is pivoted to a plate 24 supported below the body of the automobile. The lever 23 is provided with a lateral extension 25 which is connected by a link 26 with a treadle 27 mounted in a slot in the floor of the car,'the arrangement being such that when the treadle is swung in one direction the valves will be simul taneously opened, while when it is swung in the other direction they will be simultaneously closed.

A coiled spring'28 is arranged between a bracket 29 on the plate 24 and the lever, which is extended beyond its pivotal connection with the adjacent link 22, and this spring acts normally to hold the valves closed, that is, to move the lever 23 in a direction to close the valves.

Stops 30 and 31 are provided for limiting the movement of the lever in each .direction. The sand passing from the container when the valve 20 is open is delivered through a pipe 32 directly 'in front of the rear wheels, and the products of exhaustion from the engine pass also into the pipe at the point where the container joinsthe same.

In operation, when it is desired to apply sand, the treadle 27 is depressed, which causes the lever to open the valves. When the .treadle is released the valve will be closed by the It will be noticed from an inspection of Fig. 3 that a plate 33 is arranged in the said pipe, the plate extending diametrically of the pipe and at its upper end the'plate is parallel with the plane of'the ad acent wheel. The lower end of the plate is given a quarter turn, to bring said end perpen- 23 to move in a direction.

dicular to the plane of the wheel, and the lower end of the plate is split to form tongues 34, and the tongues are bent in opposite directions to discharge the sand in front of both tires of a double tired wheel. This plate is only necessary in double tired wheels. In single tired wheels the sand may be discharged directly. It will be evident that the outwardly bent portions of the plate will deflect the sand to both sides of the center of the wheel.

A valve is arranged in the pipe 14, the said pipe having an outlet port at the valve, and by means of the valve the exhaust may be shut ofi from the sand boxes when desired, the exhaust being permitted to pass directly from the pipe 14. This valve is hinged at 36 within the pipe, and a treadle 37 is connected with the valve. This treadle is normally spring pressed by a spring 38 in a direction to close the valve, and by means of the treadle the valve may be opened, the opening of the valve closing the port.

I claim: v

1. A sanding device for automobiles comprising asubstantially hopper shaped con tainer for each rear wheel, each container having means for securing the same to the running-board 1n front of the wheel, each menses container having a delivery spout at its bottom and a valve between the spout and the container, means for simultaneously opening the valves, a spring for closing the valves, each container having an inner wall spaced apart from the outer wall, the space between the walls communicating with the delivery spout, each container having an inlet at its top for the exhaust, and a layer of corrugated material between the walls.

2. A sanding device for automobiles comprising a substantially hopper shaped container for each rear Wheel, each container having means for securing the same to the running-board in front of the wheel, each container having a delivery spout at its bottom and a valve between the spout and the container, means for simultaneously opening the valves, a spring for closing the valves, and means for heating the containers with the exhaust.

3. In a sanding device for automobiles, a container for the sand having a delivery spout at its bottom, and having an inner wall spaced apart from the outer wall and communicating at its bottom with the delivery spout, said container having an inlet for the exhaust near its top, and a lining of corrugated material between the walls.
